Wheel securing structure of trucks

ABSTRACT

This invention is related to a wheel securing structure of trucks. The securing structure mainly install iron screwshaft liners on keyholes of the mounting parts of the aluminum rims. The bolts of the assembling part correspondingly penetrate the holes of the screwshaft liners each. A first folded edge and a second folded edge are formed on two terminals of the screwshaft liners to respectively insert into the conical pits of the mounting part of the rims. The nuts screw onto the bolts of the assembling part to secure the rim onto the assembling part and the nuts. When the trucks pass bumping roads, the relative motion, caused by vibrations, is occurred between the rims and the assembling part. Therefore, friction is generated between the wheels and the bolts, as well as the nuts and the terminal surfaces of the assembling part. The screwshaft liner is used to let the friction above act on the screwshaft liner. Therefore, the soft aluminum rim will not be directly rubbed by the bolts, nuts, and the assemble part to be damaged. Accordingly, the aluminum rim can be suitable for the trucks and other heavy vehicles.

BACKGROUND

Field of Invention

The disclosure relates to a wheel securing structure of trucks. Moreparticularly, an easy structure design is used to let the aluminum rimscan be used in trucks and other heavy vehicles.

Description of Related Art

At present, the wheels and drive shafts of vehicles are assembledthrough rims. Nuts and bolts are used to screw the wheel drive shaftsand rims, and then tires are assembled on the rims. Accordingly, whenthe drive shaft is rotated to drive the wheels to move the vehiclesforward.

Iron rims are mainly used in traditional vehicles. However, the weightof the iron rims is heavier. Therefore, more energy is consumed when thevehicles advance. The heat dissipation of the iron rims is also poorerto cause the tires to be blown out easily. Moreover, the iron rimseasily rust. Therefore, wheel covers are used to cover the iron rims toincrease the aesthetics of the vehicles. In light of the many drawbacksof the iron rims, practitioners research and develop aluminum rims. Thealuminum rims are light weighted to save the energy when the vehiclesadvance. The heat dissipation of the aluminum rims is excellent toprevent the tires from being blown out. Moreover, the surfaces of thealuminum rims can be polished and electroplated to have a bright andbeautiful look. The wheel covers are thus no longer needed. Therefore,the aluminum rims are commonly adopted by common vehicles.

However, heavy vehicles, including trucks, combination trucks, andcontainer trucks, still use iron rims. The main reason is that the wheelrims of the heavy vehicles are bigger than the wheel rims of the commonvehicles. When the heavy vehicles pass bumping roads, the wheel rimswithstand greater forces. For increasing the driving safety, iron wheelswith better rigidity are used.

Therefore, in view of the present aluminum rims having advantages oflight weight, oil saving, good heat dissipation, and beautifulappearance but having drawbacks of not being capable of being used bytrucks etc., the inventors develop this invention by the many-yearmanufacturing and design experience and knowledge in the related fieldsand ingenuity.

SUMMARY

This invention is related to a truck's securing structure. The mainpurpose is to provide an easy and convenient structure design for asecuring structure of aluminum rims suitable used by trucks and otherheavy vehicles.

For reaching the purpose above, a truck's securing structure isprovided. The securing structure mainly comprises an aluminum rim. Thealuminum rim comprises a mounting part, a rim part formed on a peripheryof the mounting part, a receiving space formed by the mounting part andthe rim part, and plural keyholes disposed on a central periphery of themounting part; an assembling part having an axial connection part andreceived by the receiving space of the rim, as well as plural blotsdisposed on a central periphery of the assembling part and penetratingthe keyholes of the mounting part of the rim; and plural nuts securedonto the bolts correspondingly. The truck's securing structure ischaracterized in the followings.

Plural iron screwshaft liners have a cylindrical shape andsleeve-connected to the keyholes of the mounting part of the rimrespectively to tightly match the screwshaft liners and the keyholes.The bolts penetrate the holes of the screwshaft liners, and a length ofthe screwshaft liners is longer than a length of the keyholes to let twoends of the screwshaft liners each extend out of the keyholes. Conicalpits are formed on two terminal surfaces of the mounting part andpositioned to respectively correspond to the keyholes. Two ends of thescrewshaft liners each are folded to form a first folded edge and asecond folded edge to respectively insert into the conical pits on twoterminal surfaces. The rim, the assembling parts and the nuts aresecured.

Accordingly, when the securing structure is assembled to be used, thecentral axial connection part is secured to the wheel drive shaft of theheavy vehicles including trucks. Therefore, the rim can be driven by thewheel drive shaft through the assembling part to drive the truck moveforward. When the trucks pass bumping roads, the relative motion, causedby vibrations, is occurred between the rims and the assembling part.Therefore, friction is generated between the wheels and the bolts, aswell as the nuts and the terminal surfaces of the assembling part. Thescrewshaft liners are used to let the friction above act on thescrewshaft liners. Therefore, the soft aluminum rim will not be directlyrubbed by the bolts, nuts, and the assemble part to thus damaged.Accordingly, the aluminum rim can be suitable for the trucks and otherheavy vehicles.

DETAILED DESCRIPTION

The inventors have tested the aluminum rims in trucks when the trucksadvance. As shown in FIG. 4, the damaged parts of the aluminum rim 5were mainly focused on the keyholes 51 penetrated by bolts 6, as well asthe terminal surfaces compelled by nuts 7. The main reason is that whenthe steel bolts 6 and nuts 7 contact and rub the aluminum rim 5, thekeyholes 51 and the terminal surface of the soft aluminum rim 5 areeasily expanded and deformed. Other parts of the aluminum rim 5 were notdamaged. Therefore, the structure of the aluminum rims 5 contacted bythe nuts and bolts can be strengthened to be used by trucks and otherheavy vehicles.

To more completely and clearly illustrate the technical means andeffects of this invention, the detailed descriptions are set forthbelow. Please refer to the disclosed figures and the reference numbers.

First, please refer to FIG. 1, which shows the truck's securingstructure of this invention mainly having a rim 1. The rim 1 has amounting part 11 and a rim part 12 formed on a periphery of the mountingpart 11. A receiving space 13 is formed by the mounting part 11 and therim part 12. Plural keyholes 14 are disposed on a central periphery ofthe mounting part 11. An assembling part 2 has an axial connection part21 secured and connected to a wheel drive shaft. The assembling part 3is disposed in a receiving space 13 of the wheel 1. Plural blots 22 aredisposed on a central periphery of the assembling part 2 and penetratingthe keyholes 14 of the mounting part 11 of the rim 1. Plural nuts 3 torespectively secure on the bolts 22 correspondingly. The truck'ssecuring structure is characterized in the followings.

Plural iron screwshaft liners 4 have a cylindrical shape andsleeve-connected to the keyholes 14 of the mounting part 11 of the rim 1respectively to tightly match the screwshaft liners 4 and the keyholes14. The bolts 22 penetrate the holes 41 of the screwshaft liners 4, alength of the screwshaft liners 4 is longer than a length of thekeyholes 14 to let two ends of the screwshaft liners 4 each extend outof the keyholes 14. Conical pits 15 are formed on two terminal surfacesof the mounting part 11 and respectively correspond to the keyholes 14.Two ends of the screwshaft liners 4 are folded to form a first foldededge 42 and a second folded edge 43 to respectively insert into theconical pits 26 on two terminal surfaces. The rim 1, the assemblingparts 2, and the nuts 3 are secured and positioned.

The nuts 3 are against the first folded edge 42 to be positioned. Theterminal surface of the assembling part 2 is against the second foldededge 43 to be positioned.

Please refer to FIGS. 2 and 3 together. When the securing structure isassembled, the axial connection part 21 of the assembling part 2 issecurely connected to the wheel drive shaft of the trucks and otherheavy vehicles and thus assembled with the rim part 12 of an aluminumrim 1 pre-installed with a tire. Before assembling the wheel 1 and theassembling part 2, several screwshaft liner 4 are sleeved in thekeyholes 14 of the mounting part 11 of the wheel 1 one by one to form atightly matched assembly with the keyholes 14. Subsequently, the firstfolded edge 42 and the second folded edge 43 are formed by using afixture punching on the two extending terminals projecting from thekeyholes 14. The first folded edge 42 and the second folded edge 43 arecorrespondingly insert into the conical pits 15 on the two terminalsurfaces of the mounting part 11. The rim 1 assembled with thescrewshaft liner 4 is further assembled with the assembling part 2. Theplural bolts 22 of the assembling part 2 are correspondingly penetrateto the holes 41 of the screwshaft liner 4, and the assembling part 2 ispositioned in the receiving part 13 of the wheel 1. One terminal surfaceof the assembling part 2 is against one terminal surface of the mountingpart 11 and positioned. Plural nuts 3 penetrate the holes 41 of thescrewshaft liner 4 to screw the bolts 22 one by one. The nuts 3 compelanother terminal surface of the mounting part 11 and is positioned tosecure the wheel 1 and the assembling part 2.

A truck's wheel drive shafts are rotated to drive the rims 1 with thetires through the assembling parts 1 to drive the truck move forward.When the trucks pass bumping roads, the relative motion, caused byvibrations, is occurred between the assembling sites of the assemblingparts 2, bolts 22, and nuts 3. Therefore, friction is generated betweenthe wheels 1 and the assembling parts 2, as well as the nuts 3 and thebolts 22. At this time, the screwshaft liners 4 are used to let thefriction between the wheel 1 and the terminal surface of the assemblingpart 2 mainly act on the second folded edge 43 of the screwshaft liner4, the friction at the contact rubbing sites of the nuts 3 mainly act onthe first folded edge 42, as well as the friction at the contact rubbingsites of the bolts 22 mainly act on the holes 41 of the screwshaft liner4. Accordingly, the soft aluminum rim will not be directly rubbed by thebolts 22, nuts 3, and the assemble part 2 and thus not be damaged.Accordingly, the aluminum rim 1 can be suitable for the trucks and otherheavy vehicles.

From the structure and embodiments, it can be known that this inventionhas the following advantages.

1. The securing structure of the truck's rims uses a screwshaft liner tostrengthen the structural strength of the contact sites between thealuminum rims and blots, as well as the nuts and the assembling parts.Therefore, the aluminum rims having advantages of light weight, oilsaving, good heat dissipation, and aesthetics also can be used in trucksand other heavy vehicles.

2. The truck's wheel securing structure uses a simple and easyscrewshaft liner to solve the problem of the aluminum rims being notcapable of being used in trucks and other heavy vehicles. Especially,the easy structure facilitates the assembling and practicing withoutadding too much cost, and thus the securing structure can be massproduced.
